1.randomIntegerInRange:生成指定范围的随机整数 const randomIntegerInRange = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min; randomIntegerInRange(0, 5); // 3 2.randomNumberInRange:生成指定范围的随机小数 const randomNumberInRange = (min, max) => Math.random() *...
In JavaScript, we can generate random numbers using the Math.random() function. Unfortunately, this function only generates floating-point numbers between 0 and 1.In my experience, it's much more common to need a random integer within a certain range. For example, a random number between 10...
functiongetRandomNum(min, max){returnMath.random() * (max - min) + min; } // random number in range 5(inclusive) and 10(exclusive)varrandom_num = getRandomNum(5,10);console.log(random_num);// random number in range 0(inclusive) and 100(exclusive)varrandom_num = getRandomNum(0,1...
return Math.floor(Math.random() * (max - min + 1)) + min; } getRandomInRange(10, 100); // => 63 真假随机 大家可能都玩过这样的一游戏,抛硬币。那么不管你怎么抛,都只有两个答案,一个正面(暂把它称为真,即1),另一个则是反面(也就是假,即0)。这样的游戏,我们也可以通过一个随机函数来...
大家都知道Math.random是 javascript 中返回伪随机数的函数,但查看 MDN, TheMath.random()function returns a floating-point, pseudo-random number in the range[0, 1)that is, from 0 (inclusive) up to but not including 1 (exclusive) 再看ECMAScript 5.1 (ECMA-262)标准,描述如下: ...

That's all there is to generating a random number that falls within a range that you specify.The Addition of 1 ExplainedIn JavaScript, Math.random() returns a number greater than or equal to 0 but less than 1:Another way of stating that is (0 <= n < 1) where n is the number ...
var randomnumber = Math.floor(Math.random() * (maximum - minimum + 1)) + minimum;的Math.random() 从Mozilla开发人员网络文档: // Returns a random integer between min (include) and max (include) Math.floor(Math.random() * (max - min + 1)) + min; 有用的例子: // 0 - 10 ...
这里是你的函数的一个版本，它仍然使用完全相同的方法(即，一直生成数字，直到它得到一个具有正确位数的...
Generate Random Number Above value is between 0 ( inclusive ) and 1 (exclusive) We will use Math.floor to get random number within a range. Random number Between 1 and 10 Output can be equal to 1 but always less than 10 ( not equal to 10 ) , Random integer is also displayed by ...
